MARS -The Cherenkov Observatory edition

With the MAGIC experiment, the software development of the MAGIC Analysis and Reconstruction Software (MARS) has been started. In the past years, the modular concept was improved and enhanced by a full automation concept. Both together build a user-friendly and modular framework fulfilling the requirements of future observatories like small monitoring telescopes or high-sensitivity instruments. To better distinguish this enhanced development from the MARS version further developed as a MAGIC specialized analysis, we have given it the name MARS (Now: Modular Analysis and Reconstruction Software) -Cherenkov Observatory Edition (CheObs). We will show that the existing concept, together with the latest improvements and the automation concept, is well suited as a framework for future Cherenkov observatories.
